| With the capacity extend of open-pit mine, as well as the continuous improvement of macro-scale, mechanized and automatic degrees, the proportion occupied by mining and transport is becoming more and more. Optimizing transport efficiency, implementing production plan accurately are aimed for improve mine output, save cost and achieve higher economic benefits. Open-pit mine vehicles dispatching system baseed on WebGIS has been proved to be able to control transport mediums instead of production. It is an effective way to improve production efficiency and output, to low basic cost and get higher profits.This system is a software and hardware system with GPS (global positioning system), WebGIS (network geographical information system), and wireless local area network. It integrates the WebGIS technique with wireless local area network seamlessly, and realizes working in network. The B/S three-tier mode which combines GIS with WWW is adopted in the system, The tiles saved as certain form electronic map the picture effectively minishes the data transmission amount and it can browse and display the great capacity of map quickly. In the other hand, the end of browsers don't need expensive and special GIS software, so reduce the cost of the system and save the cost of maintenance.The system successfully achieved a series of functions of selective loading of the map, browsing, movement, the pointing zoom and selective zoom, display and refreshing of the whole map, dynamic positioning of the vehicle, replaying of the track, real-time supervising and tracking, role setting, menu setting,operate setting and etc. Furthermore, the realized system also can easily integrate with other information services of Web seamlessly so that set up flexible GIS applications... |
